To all whom it may concern:

lBe it known that ll, JACOB N. CoULBoURN, a citizen of the UnitedStates, residing at Federalsburg, in the county of Caroline and n Stateof Maryland, have invented certain new and useful llmprovements inScalding Apparatus, of which the following is a specification, referencebeing had to the accompanying drawings.

This invention relates to scalding apparatus and has relation moreparticularly to a device of this general character especially designedand adapted for use in canneries for-scalding tomatoes or the likewhereby the peeling of the tomatoes may be facilitated; and it is anobject of the invention` to provide a novel and improved apparatus ofthis general character wherein Ithe tomatoes or the like to be scaldedare first immersed and lt)hen caused to travel through a steam chamer.

Furthermore it is an object of the invention to provide an apparatus ofthis general character having novel and improved means whereby the waterin which thetomatoes or the like are immersed is heated through the.medium of the water or condensation within the steam chamber and throughthe medium of' a spray which is heated by the ction of the steam withinthe steam cham- 'llhe invention consists in the details of constructionand in the combination and arrangement of the several parts of.myimproved scalding apparatus whereby certain important advantages areattainedand the device is rendered simpler, less expensive and otherwisemore convenient and advantageous for use, all as will be hereinaftermore fully set forth.

rlhe novel features ofthe invention will hereinafter be definitelyclaimed.

lin yorder thatv my invention may be the better understood, ll will nowproceedto de? scribe the same with reference to the accom-l panyingdrawings, wherein- Figure 1 is a view in side. elevation illustratingascalding apparatus constructed in accordance withv an lembodiment of myinvention; Fig. 2 is an enlarged sectional view taken substantially onthe line 2=2 of Fig. l; with the sprocket chain omitted; Fig. 3 isanenlarged fragmentary view partly in elevation and partly in sectionillustrating the discharging end' of the spray pipe as herein included;Fig. 4 is a Vlongitudinal lverspeciacation of :Leners ramt. gammadi Jam,an, may,

ticalm sectional view taken through the device as herein embodied, thewater line within the tank .being indicated by dot and dash; and Fig. 5is a v1ew in top plan of the device as herein disclosed.

As disclosed in the accompanying drawings, 1 denotes a tank ofpredetermined di mensions and having its upper face open,

and in communication with the tank adjacent the bottom thereof is thepipe P leading from a suitable source of water supply and affording ameans whereby the tank may be initially filled.

Extending upwardly within the tank l is an overflow pipe 2 havingadjustablyengaged with the upper end portion thereof the receiving heador member 3 whereby the water line within the tankvl may be varied inaccordance with the necessities of practice. l

Une end of the tank l has its upper portion reduced, as at 4,toaordcommunication with the receiving chute R disposed on apredetermined incline in a direction toward the tank l and in whichbaskets or other receptacles containing the tomatoes or the like to bescalded are initially positioned and which are adapted to be forceddownwardly into the tank so that said receptacles and their contentswill -be immersed in the water withinthe tank 1. lt is to'be noted thatthe chute lR is at such elevation as to have the'water level within thetank to extend within .the chute R to a point preferably immediatelyadjacentits outer end.

Supported bythe tank l andl overlying the top thereof'at the end portion,of the tank remote from the chut; R, is a hood H provided with thehinged sides 5. whereby convenientaccess may be had therein. The innerend'of the hood His open but is normally closed by the d'epending'ap '6preferably of canvas and which is of such a length as to extend withinthe water contained in the tank l, whereby said Hap 6 serves to retainthe heat entering within the hood H but readily permits an unobstructedpassage ofthe baskets or receptacles in a manner which will hereinafterbe more fully explained. Y

ln communication with the outer end of the hood H and the adjacentportion of the tank 1, is'the inclosed lchamber or casing C ofpredetermined vdimensions andl disposed on an upward and forwardincline, the outer endA portion of which being su ported in anyconventionalmanner as indicated at 'l'.

The outer end of the chamber or casing C is open but is adapted to beclosed by the depending lap 8 also preferably of canvas which serves toprevent the undue escape of steam discharged within the chamber or cas--ing C and which also permits an unhindered of the chamber or casing,the sprocket wheel 10 around which is disposed a'sprocket chain 11 whichextends inwardly of the chamber or casing C and is disposed around asprocket Wheel 12 rotatably supported by the end of the tank 1 remotefrom the chamber or casing and at .a point below the receiving chute Rso that'the baskets discharged within the tank 1 'from the receivingchute R will be operatively engaged by the upper stretch of the chain 11and be carried thereby longitudinally of the tank 1 and through thechamber or casing C and discharged therefrom in a manner which isbelieved to be clearly appa-rentto those skilled in the art to which myinvention'appertains.

The baskets-or receptacles are received directly upon the transverselydisposed bars 14 suitably secured to the chain 11 and the bars 14carried by the upper stretch of the chain have theirextremities restingupon the guide and supporting flanges 15 carried by the side walls ofthe chamber or casing C.

One end portion of the shaft 9 extends exteriorly of the casing orchamber C and has afhxed'there-to a sprocket wheel 16 around which isdisposed a sprocket chain 17 which is also directed around a sprocketwheel 18 aliixed to the shaft 19 rotatably supported by the casing orchamberC and disposed transversely thereof. As herein embodied, theshaft 19 is provided with a pulley 20 adapted to be coupled with asuitable source of power. The sprocket 18 is loosely mounted upon theshaft 19 but is provided with a clutch face 21 with which coacts theclutch member 22 slidably mounted upon the shaft 19 butrotating'therewith. The clutch member 22 is adapted to be adjustedrelative to the clutch face 21 in a conventional manner whereby it willbe perceived that the shaft 9 may be caused to operate when thenecessities of practice so demand. j

Supported bythe top of the casing or chamber C adjacent its outer ordelivery end is a manifold M in -communication with a suitable source ofsteam supply through the medium of theconduit 23, said conduit 23 havinginterposed therein a valve 24 whereby the supply of steam may be readilycontrolled.

In communication with the manifold M are the pipes 25 preferably four innumber and which extend within the casing or chamber C and are extendedlongitudinally thereof, and it is to be noted that two of the pipes arein vertical alinement and arranged adjacent the top and bottom of thechamber or casing C respectively, while the remaining two pipes are inhorizontal alinement and arranged 'at the sides of the casing. 'Theportions of the pipes 25 within the chamber or casing C are providedwith the inwardly directed restricted openings 26 so that the steamadmitted withinsaid pipes will be discharged within the chamber orcasing C in jets and in such a manner as to effectively engage thetomatoes or the like within the receptacles passinglthrough the chamberor casing C so as to effectively scald said t0- matoes in order topermit the same to be conveniently peeled after discharged from thechamber or casing C.

In communication with the casing or chamber C adjacent the discharge endthereof and through the top of said casing or chamber, is the flue Fthrough which the steam within the casing or chamber C is adapted to beexhausted, and in order to facilitate the exhaust of said steam, I findit of advantage to arrange within said iiue the steam jet 27 or the likefor the purpose of creating a forced draft within the fiue F.

Disposed longitudinally of the casing or chamber C and preferably inclose proximity to the top thereof is a returned water pipe 28 havingone end portion in communication with the pipe P at a point above or inadvance of the valve 29 interposed in said pipe P for controlling theHow of water therethrough into the tank 1. It is to be understood thatafter the tank 1 has been initially filled, the valve 29 is adjustedinto closed position. It willbe observed that by having the supply pipe28 disposed through the chamber C, the steam within said chamber servesto heat the water in the pipe before it passes to the tank.

The opposite end portion of the returned pipe 28 extends within the hoodH and is provided with a plurality of depending branches or extensions30 having their lower ends closed and their side or longitudinal wallsprovided with the restricted openings 31 through which the water isdischar ed in jets, whereby the water within the tan l is graduallyreplenished.

In order to agitate the water within the tank 1 to assure the propercirculation thereof, I position within the tank 1 -the agitating blade32 mounted upon an extremity of the shaft 33 extending exteriorly of thetank 1 and operatively engaged, as at 34, with the shaft 35 supported bythe bracket 36 depending from the chamber or casing C and said shaft 35is operatively engaged, as at 37, with the shaft 19.

intacta Adjacent the manifold M each of the pipes 25 has interposedtherein a controlling valve 38 whereby it will be perceived that theactiont'of said pipes 25 may be independently controlled. v

From the foregoing description, it is thought to be obvious that ascalding apparatus constructed in accordance with my invention is of anextremely simple and comparatively inexpensive, nature and isparticularly well adapted for use by reason of the convenience andfacility with which it may be assembled, andl it will also be obviousthat my invention is susceptible'of some change and mod'iication withoutmaterial departure from the principles and spirit thereof and for thisreason li do not wish to be understood as limiting myself to the precisearrangement and formation .of the several parts herein Ashown incarrying out my invention in practice.
